UNISTERI HP - detail description

Individual Assembly of the Sterilizer

UNISTERI HP devices are designed for quick sterilization in health service establishments:

  • one-day surgical clinics and consulting rooms of policlinics – sterilization of all necessary materials: Instruments, glass, textile, objects made of rubber, ...
  • surgical departments of hospitals too far from the departments of central sterilization – in particular, optimization of the repeated use of necessary instruments
  • health service clinics and first aid centres where quick sterilization of sanitary material is required
  • dental practices where the necessary material volumes cannot be treated by table-top types of sterilizers
  • microbiological departments of health service establishments – sterilization of solutions in half-closed bottles, culture media, ...

General Actively Proved Quality

The steam sterilizer UNISTERI HP is designed for the health service to sterilize medical devices. The sterilizer complies with the European Directive no. 93/42/EEC as amended by the Directive no. 2007/47/EC (Class IIb medical devices), and with the appropriate standards, especially EN 285+A2. It is manufactured within a certified quality control system according to EN ISO 13485 and adjusted to the individual needs of single worksites. The pressure equipment of the sterilizer has been designed and can be produced alternatively in accordance with the European Pressure Equipment Directive no. 97/23/EC and additionally for example, with ASME Code requirements (for the USA and Canada), or AQCIQ licence regulations (for China). Validation according to EN ISO 17665-1 is performed by our accredited testing laboratory.

Intelligent Systems of Media and Working Time Savings

The low consumption factor is reflected in the models of the future. The more and more demanding legislative requirements, laying emphasis on the introduction of safe products on the market, and the more and more rising prices of the input media constitute a pressure to the rise of the operating costs of the sterilisation technique. Therefore, the low consumption of cost saving and, at the same time, comfortably equipped sterilizers is the hit and advantage of the present age. Such sterilizers have increasingly been setting a new tone in the health care facilities.

Version with Autonomous Operation

The UNISTERI HP steam sterilizers can be equipped with the system for cooling water saving by which water consumption can be reduced by about 25%. In cases of strict requirements for low sterilizer operating costs in the health-care facilities, field hospitals, or in regions with drinking water absence, this principle of cost savings might not be sufficient. Therefore, we offer a version with autonomous operation which totally eliminates the need of connecting the device to a water source. There is thus no cost of the cooling water. This version of the sterilizer is equipped additionally with an integrated cooling aggregate placed in the rear part of the device. The operation of this apparatus is controlled fully by the sterilizer automatics and requires no operating personnel. The electrical energy and demineralised water source for the integrated steam generator are sufficient for the proper steam sterilizer operation. The supply of the steam generator by demineralised water could be solved by a fixed connection to a water treatment apparatus or in an autonomous way, namely by a reservoir with the volume of approximately 25 litres. Demineralised water supply from it is controlled by the device automatics.

Air Detector

The Air Detector is a device which monitors and detects continuously the air and/or non-condensable gasses penetration and presence in the sterilisation chamber during each programme of packed materials sterilisation. The equipment of the device with this apparatus represents a higher guarantee of the sterilisation safety than the so far performed routine checks by testing programmes (Vacuum Test and Bowie&Dick Test) done once a day only before the commencement of the common operation.

An efficient vacuum pump with a standardly intergated feeding water sparing equipment saves 15% of the operating costs. A unique construction of the steam generator with an automatic desalting ensures a continuous high quality of the steam. High-quality materials ensuring a long lifetime of the device are used during the manufacture. We offer an equipment with the waste water aftercooling apparatus allowing the waste temperature setting. The device does not produce any harmful wastes. During its manufacture, ecological methods of processing are used as well. All substantial parts of the devices and the package are recyclable. The device contains 95% of stainless steel, 4% of other materials, and 1% of electrical and plastic materials. Ecological liquidation is carried out after a disassembly by an authorized person in accordance with EU regulations complying with the WEEE (Waste Electric and Electronic Equipment) Directive.
